Communicable Diseases and the Workplace [PDF]

, 2019
[Excerpt] Coming to work when we are sick raises some interesting questions: How contagious are we? Should we stay home? What could be done to prevent disease transmission to others, with its effects on absenteeism, performance, and efficiency, as well ...

Phylogenetic Analyses Suggest that Factors Other Than the Capsid Protein Play a Role in the Epidemic Potential of GII.2 Norovirus

mSphere, 2017
Norovirus is the leading cause of acute gastroenteritis worldwide. For over two decades, a single genotype (GII.4) has been responsible for most norovirus-associated cases. However, during the winter of 2014 to 2015, the GII.4 strains were displaced by a

Nanolitre real-time PCR detection of bacterial, parasitic, and viral agents from patients with diarrhoea in Nunavut, Canada [PDF]

, 2013
Background. Little is known about the microbiology of diarrhoeal disease in Canada's Arctic regions. There are a number of limitations of conventional microbiology testing techniques for diarrhoeal pathogens, and these may be further compromised ...

Emergence of new recombinant noroviruses GII.p16-GII.4 and GII.p16-GII.2, France, winter 2016 to 2017

Euro surveillance : bulletin Europeen sur les maladies transmissibles = European communicable disease bulletin, 2017
An early increase in outbreaks of norovirus gastroenteritis characterised at the French National Reference Centre occurred this winter season. They were concurrent with an unusual pattern of circulating strains, with three predominant genotypes: the re ...

Production of Brazilian human norovirus VLPs and comparison of purification methods [PDF]

, 2015
Noroviruses (NVs) are responsible for most cases of human nonbacterial gastroenteritis worldwide. Some parameters for the purification of NV virus-like particles (VLPs) such as ease of production and yield were studied for future development of vaccines ...

Structural Biology of Noroviruses

, 2016
Noroviruses constitute a major genus in the family Caliciviridae, which contains icosahedral viruses with positive-sense single-stranded RNA genome. In humans, these constantly evolving viruses are the cause of sporadic and epidemic gastroenteritis. Despite a lack of a reproducible cell culture system or a small animal model, remarkable progress has ...

Near-Complete Genome Sequences of Several New Norovirus Genogroup II Genotypes. [PDF]

, 2018
We report here the near-complete genome sequences of 13 norovirus strains detected in stool samples from patients with acute gastroenteritis from Bangladesh, Ecuador, Guatemala, Peru, Nicaragua, and the United States that are classified into one existing

Pandemic GII.4 Sydney and Epidemic GII.17 Kawasaki308 Noroviruses Display Distinct Specificities for Histo-Blood Group Antigens Leading to Different Transmission Vector Dynamics in Pacific Oysters

Frontiers in Microbiology, 2018
Noroviruses are the major cause of foodborne outbreaks of acute gastroenteritis, which are often linked to raw oyster consumption. Previous studies have suggested histo-blood group antigens (HBGA)-like structures in the oyster tissues as ligands for ...

Genetic and antigenic diversity among noroviruses

Journal of General Virology, 2006
Human norovirus (NoV) strains cause a considerable number of outbreaks of gastroenteritis worldwide. Based on their capsid gene (VP1) sequence, human NoV strains can be grouped into two genogroups (GI and GII) and at least 14 GI and 17 GII genotypes (GI/1–14 and GII/1–17).
